After completing medical school at New York Medical College I moved on to a one year Surgical internship and Anesthesiology residency at the University of Arizona. Although I loved the practice of Anesthesiology, during my residency I found my true passion in the treatment of chronic pain. I completed a fellowship in Pain Medicine at Columbia University and returned to my home in Tucson having an opportunity to practice with my good friend and mentor, Dr. Emil Annabi. It is a real privilege to return to Tucson and provide pain management to my hometown community that I have been a part of for over 20 years.
